Lifetime course of chronic depression in older men.

The lifetime course of illness in older outpatient men who remained symptomatic despite adequate pharmacologic treatment for depression was examined. A bimodal distribution of age of onset of first major depression was found, with 75% having onset before age 35 years and 25% having onset after age 50 years. At all ages, episodes of chronic depression developed after episodes of major depression and appeared to be partially resolved major depression. In 88% of patients, anxiety disorders developed before age 35 years, preceded onset of other disorders, and continued throughout the patient's lifetime. Seventy percent developed alcoholism and 25% had a medical illness that impaired function to a significant degree. The importance of obtaining a lifetime course of illness in older patients is discussed.
